Fabric is a textile material produced by weaving or knitting textile fibers. The earliest instances of cotton, silk and linen fabrics date back to around 5,000 BC in India, Egypt and China. Textiles can be derived from animal sources like wool, silk and pashmina, plant sources like cotton, and mineral sources like glass fiber. Fabrics are classified based on fiber used and can be natural like cotton, synthetic like polyester, or for various uses like apparel, home furnishings, or upholstery.
